Re: rEvo III FT RMS & Lithium 9V's

My unit is an early 2012. I have done a battery box replacement. My 9v drains very quickly. 8 hours max. Every dive I get a temp probe lost prompt. Checking the scrubber menu after shows no issues. Later in the dive the temp probe found prompt comes on. Yesterday I had a ?X come on when firing the unit up. Prebreath didnt help. I restarted the Predator a few times. Still nothing. I pulled the cover and set the canister on the CAN bus. Still nothing. I reassembled the unit, shut it down, and jumped on my phone to trouble shoot. About 10 minutes later I fired it back on, it showed green ??, registered a prebreath, so off I went.
Every dive including this one I loose and regain a temp probe. This is the first time I have had a "disconnect" when setting up.
BTW. What do the scruuber reset and force ready functions do? Manual say do not use without instructor.

Re: rEvo III FT RMS & Lithium 9V's

Sounds like what I experienced recently (still holding my breath). The red X was on the top scrubber. First, we diagnosed one of the scrubber temp probe to be the culprit (swap scrubber, the red X switches position). Replaced the temp probe, which turned out to be fine, according to Jason (he was the one coming up with the diagnostics! .
Anyway, problems continued with the new canister, so eventually Paul diagnosed bad module (solenoid one, detected by missing exhale temperature in the advanced scrubber temperature screen). Changed that and seemed to fix the problem.
However, I have had some brief "missing temp probe" events after that. Jason sent me replacement probes for this (which I haven't installed yet), but from what Paul said above (probes work or don't, they are not working intermittently), we are both experiencing a weird Pacific Ocean-specific disturbance. I suspect wireless communications scrambling by the Navy.
Note that I did not miss a dive, but I spent a lot of time typing emails and posts...

I had similar issues, Paul at the factory quickly sorted this out by replacing some parts. No issues since then.

One of my probes did the same as yours. Is it the same probe every time? If yes, try moving it to scrubber cartridge to the other "receiver" (sensor or Solenoid board) and wait about 60 seconds for the system to register it. If the temp-probe is the issue, then the display should switch from ?X to X?.

Re: rEvo III FT RMS & Lithium 9V's

my quote 'probes work or don't work' was related to higher battery consumption

it can sometimes be that there is intermittent loss of communication: check that the probe is installed so that the transmitter element is exactly at the outer surface of the nut that holds the probe (it should not be inside the nut)

Re: rEvo III FT RMS & Lithium 9V's

What happens with people who own early 2012 units, are their components replaced if they show signs of problems?

BTW - Thanks for being so accessible on these forums and willing to both help and explain problems without trying to hide them - excellent support!

we already apply extended warranty for these components from early 2012 units: if they encounter problems, the parts are replaced.

(ofcourse first we ask to do some diagnostics, as there is no reason to just 'replace' everyting )

What are we calling early 2012 ? I "think" mine was about May/June but cannot remember. If I email the factory my details can they tell me which I have or is there an easy way to tell by looking at it ?
